Top 5 Myths About Surge Protective Devices Debunked

Surge Protective Devices (SPDs) are often misunderstood, leading to costly decisions and vulnerabilities. Let’s clear up five common myths.

Myth 1: Power Strips Provide Surge Protection

Fact: Most basic power strips don’t have built-in surge protection. Always check for SPD labeling or certifications.

Myth 2: SPDs Last Forever

Fact: SPDs degrade over time, especially after multiple surge events. Routine inspection and replacement are essential.

Myth 3: Only Lightning Requires Protection

Fact: Most surges come from internal sources like HVAC systems or motor switching. Everyday protection matters.

Myth 4: One SPD Protects the Whole Building

Fact: A layered approach using SPDs at multiple points (main panel, subpanels, devices) is most effective.

Myth 5: Surge Protection Is Too Expensive

Fact: Compared to the cost of equipment damage, downtime, or data loss, SPDs are a wise investment.

Don’t let misinformation put your electrical systems at risk. Invest in proper surge protection.
